Atmosphere | A MIXTURE OG GASES THAT SURROUNDS A PLANET OR MOON |
Air pressure | THE MEASURE OF THE FORCE WITH WHICH AIR MOLECULES PUSH ON A SURFACE |
Wind | THE MOVEMENT OF AIR CAUSED BY DIFFERENCES IN AIR PRESSURE |
Global winds | The combination of convection cells found at every 30 of latitude and the coriolis effect produces patterns of air circulation |
Land breeze | During the day the land breeze is warm and creates a low pressure but in the night the breeze is cooler and moves towards the ocean |
Sea breeze | During the day the air is cooler and forms a high pressure at night the air is warmer and has a low pressure |
Coriolis effect | The apparent curving of the path of a moving object from an otherwise straight path due to earthâs rotation |
Air mass | A large body of air where temperature and moisture content are constant throughout |
Continental | Forms over land |
Maritime | Forms over water |
Tropical | Develops over tropics |
Polar | Forms over the polar regions |
Warm front | When warm air moves over cold |
Cold front | When cold air moves over warm air |
Occluded front | When warm air mass is caught between two colder air masses |
Stationary front | When a cold air mass meets a warm air mass |
Hurricane | A severe storm that develops over tropical oceans and whose strong winds of more then 120 km/h spiral in toward the intensely low pressure storm center |
Thunderstorm | A usually brief, heavy storm that consists of rain, strong winds, lightning, and thunder |
Tornado | A destructive rotating column of air that has very high wind speeds p, is visible as a funnel-shaped cloud and touches the ground |
